A 34-year-old man being sought in a woman 's death has been arrested in connection with the killings of two homeless men who were shot three days apart while both were sleeping on sidewalks , Atlanta police said Friday .

Aeman Lovel Presley was in custody , but police were n't providing further details about his arrest , said Sgt. Greg Lyon .

Presley , of Atlanta , also was wanted by police in Decatur , Georgia , in the fatal shooting Saturday night of a 44-year-old woman whose body was found behind an office building , according to police and CNN affiliate WSB .

An arrest warrant for Presley was issued in the Decatur case , Decatur police Sgt. Jennifer Ross said Friday .

`` We are actively working with multiple agencies at this time and can not provide any further information that may jeopardize ongoing investigations , '' Ross said .

Karen Pearce , a hair stylist in Marietta , was shot shortly after she left a restaurant in downtown Decatur , the affiliate reported .

True Salon , where Pearce worked , said on its Facebook page Friday that `` while we are relieved to hear that a suspect is in custody , we are still trying to comprehend this senseless act of violence that took a very special person from our lives . ''

Presley or his attorneys could n't be immediately reached for comment Friday .

Atlanta police called the shootings of homeless men `` sinister '' because whoever pulled the trigger was n't expecting to gain from the victims monetarily .

`` A lot of our shootings involve robbery . A lot of our shootings involve someone making good on an old debt or some kind of revenge factor , '' Atlanta police Detective David Quinn told reporters earlier this week .

`` I do n't know why someone would shoot two defenseless men . ''

The shootings happened during Thanksgiving week , within three days of each other .

Three days , 3 miles apart

In the homeless men case , the first shooting took place November 23 .

Dorian Jenkins , 42 , was fatally shot five times as he slept , wrapped in a blanket , on a sidewalk in downtown Atlanta .

Less than three days later , Tommy Mims , 64 , did n't show up as normal at a recycling center where he took cans and other scrap metals to sell .

Mims , known locally as `` Can Man '' was found dead under a bridge where he usually slept . His body , also wrapped in a blanket , had seven gunshot wounds . He was killed less than three miles from Jenkins .

`` They never came out of the sleep they were already in , '' Quinn said . `` They were n't fleeing , running . They were asleep when they took these rounds . ''

Telling details

Police say evidence links the killings of the homeless men .

The rounds used in both shootings are fairly distinctive : .45 - caliber bullets that , according to Quinn , have n't been made since 2010 .

They were fired from revolvers , either a Taurus `` Judge '' or a Smith & Wesson `` Governor . '' That reveals another troubling fact .

`` These guns have a capacity of five or six rounds , '' Quinn said . But Mims , the second victim , had been shot seven times .

`` Someone had to reload the gun in order to get seven rounds in him . ''
